CVE-2024-26790

5.5 · MEDIUM
Published Apr 4, 2024 linux CWE-667 EPSS 0.17% (7th pctl)

Overview

CVE-2024-26790 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 4, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: fsl-qdma: fix SoC may hang on 16 byte unaligned read

There is chip (ls1028a) errata:

The SoC may hang on 16 byte unaligned read transactions by QDMA.

Unaligned read transactions initiated by QDMA may stall in the NOC

(Network On-Chip), causing a deadlock condition. Stalled transactions will

trigger completion timeouts in PCIe controller.

Workaround:

Enable prefetch by setting the source descriptor prefetchable bit

( SD[PF] = 1 ).

Implement this workaround.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
